这篇文章是作者和他的许多同事从致力于形成一种迷人的材料--丝状碳的研究中获得的信息的综述。使用可控气氛电子显微镜技术，可以直接观察各种金属和合金颗粒催化这种形式的碳的生长的方式。基于从这些实验中获得的定性和定量数据，开发了一种机制来解释丝状碳的生长特性。通过对该过程中所涉及的关键步骤的考虑，已经有可能建立控制这些结构生长的方法。对许多生长序列的连续观察表明，向催化剂中加入第二种金属以及金属-载体相互作用的强度都可以在改变细丝生长特性方面发挥重要作用。
This article is a review of the information obtained by the author and his many co-workers from studies devoted to the formation of a fascinating material, filamentous carbon. Using the controlled atmosphere electron microcopy technique it has been possible to directly observe the manner by which various metal and alloys particles catalyze the growth of this form of carbon. Based on the qualitative and quantitative data obtained from these experiments, a mechanism was developed to account for the growth characteristics of filamentous carbon. From a consideration of the key steps involved in the process it has been possible to establish methods for controlling the growth of these structures. Continuous observation of many growth sequences has shown that both the addition of a second metal to the catalyst and also the strength of the metal-support interaction can play an important role in modifying the filament growth characteristics.
